Get me Warmack from Alabama. He may be rated #3, but guards drop because of their position, like Decastro did last year.
If he's still around, take him and immediately plug one hole in the O-line. If Warmack is gone, take Cooper.
Not likely to happen, but I would follow up with Barrett Jones in the second round. With the o-line problems solved, go D-line, RB and safeties in the next few rounds.
